fcmaINED TIRE-'VALVE Nn PRESSURE-GAGE.

To all whom z't may concern: v

Be it known that I, OsoAR F. It. BROM- nnnm a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful' Improvements in Combined Tire-Valves -and Pressure-Gages, of which the following is a specication.

vMy invention relates to a combined Itire valve and pressure gage for pneumatic t1res. The Vobjects of my invention are, first,

`to providea combinedtire valve and presi sure gage by the use of which the amount of'pressure `1n the tire may be readily ascer-` tained while it is being filled or at any other time as desired; second, to provide a newand novel construction of tirevalve;=th1rd,

toprovide a new and novel construction of 1 pressure gage to be used in connection with which the scale of the pressure gage may be v turned to any positiondesired relatively to l ple andeconomical of construction, durable,

said tirev valve; fourth, to provide such a combined tire valve andA pressure gage in the tire when placingl the same in position on the tire, and th, .to provide such a combinedtiieand pressure gage which is simeasily installed and does not readily get out of'orde'r. -5- i ,y p l With these andotherobjects iii-view as `will appear hereinafter, my invention. con-1 sists of certain novel features of construction, combinationand arrangement of arts as will -be hereinafter described in etail and particularly set forth in the 'appended claims, reference being had to the accomf pal partsvofLmy device.

'of reference thereon which form a panying drawings and to the characters part of this specification, in which: l Y Figure l, is a side elevational view of my device complete, showing a portion of the cap broken away to illustrate the pressure scale; Fig. 2, is a sectional view thereof at right'angles -thereto and Fig. 3, is a detaill enlarged .sectional View of the tire Ivalve.

Similar characters of reference refer Ito similar parts throughout the several views. The base piece 1,' intermediate piece 2, cap

3, dust.cap4,ycylindrlca1 piece' 5, plug 6,

spring .7, indicator piece 8, lunger 9, valve 10, valve rod 11, valve sprmg 12,|scale 13, and air conductor 14 constitute theprin'ci- AThebase piece '1 is preferably hexagon shaped, adapted for a wrenchv facilitate spcification of retten Patent'.

'- its turningion the air conductorli. It is conductor 14. In the vupper portion of said base piece l is provided a lar er hole 2 which extends to the hole 1 which 1s adapted for the intermediate piece 2. This hole is-provided with an annular recess 1 adapted for the collar 2 around the lower end of said inter'- mediate piece 2. Between the air conductor 14`and the intermediate piece 2 is provided a gasket 14 adapted to provide a tight t between the end 'of the air conductor 14 and the intermediate piece 2. This intermediate piece 2 is provided centrally with a hole 2 extending longitudinally therethrough and with a chamber 2*? in one side thereof extending longitudinally therein. This chamber is provided with a slot 2 in one side thereof extending through the wall between the chamber 2d and the outer surfaceof the intermediate piece 2.. Between thev lower end of this chamber 2d and the end of the intermediate piece 2 is provided a port 2t adapted to allow the air to enter the cham` ber 2d from the tire or from the hole 2 when there is a certain pressure in the tire or whenair i's being pumped into the tire. In the upper end of this chamber 2`is secured p the cylindrical piece 5 by means ofA a threaded part screwed into threads in the top end of the chamber 2. This cylindrical piece lrest in and with a similar groove in its up per surface adapted for the ends of the screws 5 which extend through and are screwed into thel upperl projectin portion of the cylindrical piece 5- and a apted to adjust the washer 5b in certain positions for adjustin the tensionof the spring 7. Mounted in t e lower end of the chamber 2d is provided the plunger 9 which comprises metallic washers 9 and flexible or elastic washers 9, preferably leather. Secured-,to this plunger 9 by means of the bolt 9 is the plug 6 which is adapted to telescope into the lower end of the'cylindrical iece 5, said cylindrical piece 5 and said -p ug, serving asv a. core for the spring 7. Y f

Mounted between the plug 6.A and the up- I' per washer 9 is the indicating piece 8 which is'in the form of a spider with one of its members extending outwardly at point 8a adapted to move longitudinally 1n the slot -2e for indicating the pressure in the tire by means of the scale 13 on the outer surface of the intermediate piece 2 adjacent the sides of said slot as the plunger 9 is raised and lowered in the chamber 2 by means of the air ressure through theport 2f.

, ounted on the top end of the intermediate piece 2 by means of threads is the cap "piece 3 which-is provided with a plurality' of annular recesses 3a adapted for the ends of the screws 5. This cap piece 3 is provided with acentral hole 3b conforming to the hole 2"l in the intermediate piece 2. Near the lower surface is provided an enlarged portion 3c forming a recess for the spring 12. The lower end of said spring is mounted on a gasket 12 which is adapted to prevent leakage between the intermediate iece 2 and the cap 3. The other end of sai spring 12 engages with a small. flattened portion 11aon the rod 11. On the upper end of this cap 11 is provided a threaded portion 11b adapted for the nozzle of the air hose. The

l valve rod 11 extends from slightly above the upper end of said cap 3 downwardly through the hole 3b and 2c and on its lower end vis secured the tire valve 10 which comprises v a metallic piece 10 covered withv a pliable clude in the purview of my invention theconstruction, combination and arrangement substantially as set forth in the appended claims.

It is obvious that with this construction there is provided 'a combined tire valve and pressure gage for testing the pressure in tires; that is simple and economical of construction, durable, easily installed and easily operated.; that the device tis adjustable throughout and consists o fseparate chambers, the one for the a'ir pressure gage and the other for lthe tirevalve operating mechanism, that the scale may be adjusted'4 to any position 4when placing the device on the tire by reason of the swivel connection .between the base piece 1 and the intermediate piece 2. Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is Y 1.- In a combined tire valve and pressure gage, the combination of a base piece7 an intermediate piece mounted therein provided with a valve seat at its lower end and a central hole longitudinally therethrough serving as an air conductor and with a chamber disposed in' one side thereof with a port, said port andcentral hole terminating in said valve seat, an airvalve covering the lower end of saidcentral hole and said port in said valvefseat, a plunger reciprolcally mounted in v said chamber, yielding means engaging with said plunger and means for indicating \the pressure on said plunger in connection with said plunger.
